A student claims a bodysuit she ordered online had hair and skidmarks on it when it arrived.
Olivia Freeman ordered the pink garment from Pretty Little Thing for £18, but was horrified by what arrived.
The site boasts the outfit would would give buyers a "totally fierce look".
But when it arrived the protective sticker over the crotch area was loose.
The 22-year-old then said she spotted a suspicious brown mark and a hair inside.
Olivia - who is studying sports rehabilitation at Plymouth Marjon University - said: "I opened it and was mortified, it was just vile.
"In the crotch area the sticker not even attached, with hairs stuck to it. They were blatantly pubes, little black curly ones.
"Then I noticed the brown skid marks where someone had obviously tried this on after not wiping properly.
"It was vile."
She returned the soiled Pink Stretch Satin Cup Bodysuit - which she got £4 student discount on - and asked for her money back.
She also wrote to Pretty Little Thing on Twitter , explaining that the bodysuit was for her holiday and she was running out of time to order another one.
Olivia said: "All they said on Twitter was sorry, if you send it back we'll refund you."
She ordered another two similar bodysuits as a replacement but one also didn't meet her expectations.
The Baby Blue Lace Cup and Panel Satin Bodysuit had a hole in it.
When Olivia, of Dorchester, Dorset, tried it on her nipple was left poking out.
"I loved them both, then discovered that there was a hole right on my nipple on one of them," she said.
"My actual nipple was poking out of the top."
Olivia has sent the second bodysuit back to Pretty Little Thing as well and hopes she will be refunded.
Pretty Little Thing has been approached for comment.
